Google Assistant is rolling out in Brazil with Brazilian-Portuguese
Google Assistant may be over a year old now, but it still only supports a select number of languages in a few countries. Back in May at Google I/O, it was announced that Assistant would support four more languages, including Brazilian-Portuguese, by the end of the summer. Lo and behold, Google Assistant in a Brazilian-Portuguese flavor is now available in Brazil.
Google's support page for this hasn't been updated yet, as Portuguese is still listed under the list of upcoming languages for both non-Pixel and Pixel Android devices. If you haven't already gotten around to setting it up, a notification should have appeared on your device; if not, you can try long-pressing the home button to see what happens. After going through a quick tutorial, you should be able to use Assistant to its full extent, which includes answering questions, searching your screen, finding nearby restaurants, and so on.
Let us know in the comments if you're in Brazil and now have Assistant. We've had a few tips about this, so the rollout shouldn't be super limited.
